Shadows of Undrentide expands the Neverwinter Nights universe with new features such as Prestige Classes, new spells and feats from the 3rd edition Dungeons and Dragons rulebooks. The story line is in no way related to the first game; infact, the game is made for you to start with a new character rather than continue with a previous. You start as a student of Master Drogan, a retired adventurer. After Drogan is incapacitated, your character departs to find a cure for him. You must follow a trail of clues, solving puzzles and battling enemies from kobolds to dragons to save him.
